Picconia is a genus of two species flowering plants in the family Oleaceae, found in the laurel forests habitat, of Macaronesia.[1]

Description

They are evergreen shrubs to trees with large, opposite, entire, shiny, ovoid leaves and numerous flowers. The fruit is a drupe. The flowers are small white and fragrant, followed by one-seeded, olive-like green fruit, ripening to bluish-black.[2] Picconia are native of open spots in the laurel forest of the Canary Islands and Madeira where they are found only in the humid to hyper-humid evergreen forests of the cloud belt.[3] Tree species with laurel-shaped leaves are predominant, forming a dense canopy up to 40 m high that can be hardly trespassed by light, which results in scant vegetation in the understory.[3] Most of these tree species in Africa are ancient paleoendemic[4] species of the genera Laurus, Ocotea, Persea, and Picconia, which in ancient times were widely distributed on the African and European continents.[3][4]
